"After finishing the Opening Ceremony, I hardly knew what day of the week it was. I took a month off work, off music, off everything," Smith said.

"Exactly one month and three days after we said goodbye in the stadium, I received a text from Danny that said, 'Do you ever want to hear from me again workwise and would that go as far as having a chat about Trance... questions, questions'. Two minutes later I was on board."

"I was honoured to be asked to collaborate with him again for the film and, with his help, I believe we have created something very special."

Boyle added: "Trance reaches back to the darker, more anarchic spirit of films like Trainspotting on which Rick was a key collaborator.

"The film is a puzzle of the protagonist's own making and Rick's music brilliantly drives the interior landscape of these characters as they try to solve it."

Smith continued: "For a film composer, working with Danny is a joy, because he's both a great collaborator and a giver of artistic freedom, he loves to be surprised, and also wants his film music loud and with presence, almost like another character - for me this is creatively exciting and inspiring.

"And it was a real joy to work with Emeli again - her passionate soulful voice and wonderful lyrics are a perfect ingredient of the score."
